Abstract
Spin/valley dependent dwell time in 8-Pmmn borophene junction under Rashba spin–orbit interaction (RSOI) is studied. The dwell time as well as transmission probability for incident electrons with spin-up show a different behavior than the incident electrons with spin-down, and these quantities can be controlled effectively by the junction direction, incident angle, the RSOI strength and the barrier width. Also, the dwell time is dependent on the degree of freedom of the valley and shows oscillating behavior with the increase of the barrier width. The spin polarization and spin filtering in 8-Pmmn borophene junction under RSOI can be obtained in the time domain.
期刊介绍：
Physica Scripta is an international journal for original research in any branch of experimental and theoretical physics. Articles will be considered in any of the following topics, and interdisciplinary topics involving physics are also welcomed:
-Atomic, molecular and optical physics-
Plasma physics-
Condensed matter physics-
Mathematical physics-
Astrophysics-
High energy physics-
Nuclear physics-
Nonlinear physics.
The journal aims to increase the visibility and accessibility of research to the wider physical sciences community. Articles on topics of broad interest are encouraged and submissions in more specialist fields should endeavour to include reference to the wider context of their research in the introduction.
